Abstract: Tensor network states are new kinds of variational wavefunctions that help us to understand quantum phases and phase transitions beyond Landau paradigm. In this talk, I will first review th...
Abstract: We introduce the notion of quantum Markov decision process (qMDP) as a semantic model of nondeterministic and concurrent quantum programs. It is shown by examples that qMDPs can be used in ...
Abstract: We use quantum discord to characterize the correlations present in the model called deterministic quantum computation with one quantum bit (DQC1), introduced by Knill and Laflamme [Phys. Re...
Abstract: Title: Trapping Rydberg Atoms in an Optical Lattice Abstract: Rubidium Rydberg atoms are laser excited and subsequently trapped in a one-dimensional optical lattice (wavelength 1064 nm). ...
Abstract: Entanglement is considered the most characteristic trait of quantum mechanics. Nonetheless, almost all states---including unentangled ones---of bi-and multi-partite systems exhibit some qua...
Abstract: We have observed the Bose-Einstein condensation of an atomic gas in the (quasi)uniform threedimensional potential of an optical box trap. Condensation is seen in the bimodal momentum distri...
